Check Max Axis Velocity -- For inverse time feed mode, the postprocessor uses the FEDRAT command currently in effect and the distance it calculates for the next move in the formula VELOCITY/DST (where velocity is feed in UPM even if input is in UPR mode). Very short moves can cause conditions where the inverse time value calculated exceeds the machines ability to make the motion at this calculated feedrate even though the calculated value falls within the maximum values specified on this panel. To limit the maximum inverse time value calculated for short moves, enter the "minimum" time value that is to be used by the postprocessor for the calculation in either minutes or seconds as required. Any moves that would be made in less than the time value specified would substitute the specified time in the calculation. When Auto is selected, the GPost finds the minimum time for each axis and compares the min-max feedrate settings and adjusts the programmed feedrate automatically. When Disable is selected, the time value is 0. (Intcom 2720, Dblcom 887)
